Study Design: simple retrospective with cross-sectional design approach. Place and Duration of Study: Retrospective data of LBWB obtained from newborn medical record (year 2017-2022) of The Sultan Thaha Saifuddin Tebo Regional Public Hospital, located in Jambi-Indonesia and analysis conducted in the Departemen Kedokteran Komunitas (Community Medicine), the Faculty of Medicine, Universitas Kristen Indonesia, Jakarta Indonesia, between September-November 2023. Methodology: The inclusion criteria focus on all newborn with LBWB that have complete medical record data. The acquired data regarding (1) maternal age, gestational age at the time of giving birth, Hb level prior to delivery, (2) newborn: gender, survivability and birth weight. All respondents will be subjected to statistical analysis using the SPSS programme and Microsoft Excel 2016. The exhibited information consists of data distribution presented in the form of tables and utilising univariate analysis and regression testing. Results: Analysis of 256 LBWB data (122 (47.65%) boys, 134 (52.34%) girls) revealed that in the maternal side mean age 28.54 years old, mean gestational age 36.07 weeks at the time of giving birth and mean Hb level 10.8 gram/dL. In the newborn side viability were 226 (88.33%) viable and mean overall birth weight 1990.2 g. Statistically using Pearson correlation, there is a very weak correlation firstly among maternal Hb count with the neonates primary weight (P = 0.00, r = 0.154) and secondly between gestational age and the birth weight of newborn (P = 0.00, r = 0.000). From the community medicine perspective, Efforts to increase the Hb levels of pregnant women theoretically can be carried out more easily by encouraging and increasing the mother's and also their partners, families and society awareness of carrying out routine antenatal care, encouraging the role of health motivator/local health cadre and conducting Hb examination as simple screening; all of them supported by the government. Conclusion: Maternal low Hb count and gestational age correlate with birth weight of newborn. Further in depth and extensive study needed to explore specific factors contribute to the incidence of anemia in mother who gave birth neonates which have low birth weight (LBW) and their impact to pregnancy.","PeriodicalId":249518,"journal":{"name":"International Blood Research & Reviews","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139144765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hepatitis D (Hepatitis Delta) is a disease caused by the hepatitis D virus (HDV). It is considered to be a sub viral satellite because it can propagate only in the presence of the hepatitis B virus. The prevalence of HDV in Port Harcourt has not been reported; hence this study, bridge that knowledge gap. \u0000Methods: Using a qualitative cross sectional study design, a general serological screening test was performed on a total of 300 blood donors recruited; 222(74.00%) males and 78 (26.00%) females, all within 20-59years. Of this number, 86(28.70%) were positive for HBV while 214(71.30%) Hepatitis B negative served as control. Samples collected were analysed at blood bank unit of the Haematology Department of the Rivers State University Teaching Hospital, Port Harcourt (RSUTH). Hepatitis B surface antigen (HBsAg), and anti-hepatitis D antibodies (anti-HDV) for the presence of HBV and HDV infections were detected by one step Hepatitis B surface antigen (HBsAg) in serum, and enzyme linked immunosorbent assay for the detection of HDV as described by the www.elabScience.com (16). \u0000Results: Of the 300 subjects, 86(28.6%) were positive for Hepatitis B surface antigen (HBsAg). Of these HBV positive subject, 9(10.4%) were positive for Hepatitis D virus (HDV). Age and gender of the study participants were not found to be risk factors for its prevalence (p > 0.05). There was no statistically significant difference in the PCV of those infected when compared with the non infected group. Using Pearson correlation analysis, HDV was not found to associate significantly with PCV (r = 0.2849, p > 0.05). This study recorded HDV prevalence rate of 10.4% among the HBsAg positive blood donors. \u0000Conclusion and Implications for Translation: There is a 10.4% prevalence of HDV among the HBsAg positive blood donors. To increase the safety level of blood products, the screening process should therefore be extended to the HDV. ","PeriodicalId":249518,"journal":{"name":"International Blood Research &amp; Reviews","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133615904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current storage regulations make this product highly susceptible to bacterial contaminations and platelet storage lesions (PSL) causing the need for alternative storage methods to be considered. The implementation of cold storage not only reduces unnecessary wastage of valuable donations and overall costs but also decreases both the risk of bacterial contamination and the occurrence of PSL. The current study aimed at determining how a prolonged cold storage may affect PCs. This was accomplished by investigating two different PC cohorts of 10 units each. One of the cohorts, labelled as ‘Room Temperature’, was stored at 22℃±2℃ for 5 days and then transferred to a temperature of 4℃±2℃. The other cohort, labelled as ‘Cold’, was stored directly at 4℃±2℃. Both cohorts were stored for a total of 21 days and platelet indices, platelet counts, pH, and platelet factor IV (PF4) were measured at different time intervals. Sterility was performed on Day 21. The key findings showed no significant difference in mean platelet count, platelet distribution width (PDW), mean platelet volume (MPV), platelet-large cell ratio (P-LCR), and plateletcrit (PCT) between the two cohorts. On the other hand, a significant difference in mean pH and PF4 resulted between the two cohorts. Moreover, no significant difference in mean platelet count, and PCT was found between Days 1, 5, or 10, and Day 21 in both cohorts. However, an overall significant difference in mean PDW, MPV, P-LCR and pH was discovered between Days 1 and 21, Days 5 and 21, and Days 10 and 21 in both cohorts. Regards PF4, a significant difference was detected between Days 1 and 21, and Days 10 and 21; however, no significant difference was found between Days 5 and 21 in both cohorts. Corynebacterium freneyi and Microbacterium liquefaciens, were cultured from 1 unit of the room temperature cohort after it was flagged positive during the sterility testing. In conclusion, through the implementation of a delayed cold storage system, PCs can be safely administered to the patient.","PeriodicalId":249518,"journal":{"name":"International Blood Research &amp; Reviews","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129385817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MMA is an in vitro simulation of the behavior of the antibodies, demonstrating the reactions that would occur in the endothelial reticulum system after a transfusion of incompatible red blood cells, indicating the risk of a hemolytic transfusion reaction and therefore of the clinical significance of the antibodies. \u0000Study Design: Blood samples of alloimmunized patients, selected at random from a blood donation bank, were submitted to validation tests recommended by the Brazilian National Health Surveillance Agency for the approval of new testing procedures. \u0000Place and Duration of Study: The following Brazilian institutions were involved between June 2009 and July 2010: Immunohematology laboratory of the Hematology and Hemotherapy Center of Santa Catarina state in Florianópolis, Department of Medicine (Medical Unit IV) and Department of Radiology of the Institute of Medical Sciences, Hospital Lahore in São Paulo. \u0000Methodology: Ninety samples of alloimmunized patients treated by the Santa Catarina blood donors were used. The validation tests evaluated the selectivity, linearity, precision, and accuracy of the MMA method and determined the limits of detection and quantification. External validation of the method was performed by comparing these results with those of an independent laboratory in São Paulo, while making sure that the latter was blind to the results of the former. The coefficient of variation was used to express the MMA testing precision of 5 replicates across 5 different concentration levels. Type I error for evaluating statistical significance was set at 5%. \u0000Results: Selectivity assessment of the impact of multiple alloantibodies on the MMA test result showed no statistically significant difference (P>0.05) across the titers of 64, 256, and 2048, each with three replications, thus confirming the test specificity. Homoscedasticity of the monocyte index (MI) data was not refuted by Levine's test with the F-value of 0.746, much below the value of 3.056 needed to achieve a statistical significance level of P<0.05. MI linearity against the logarithm of the alloantibody concentration was shown in a simple linear regression where the latter predicted 83% of the variation in the former, and the regression slope of 0.4 (95% confidence interval 0.32, 0.48). The limits of detection and quantification on the logarithm scale were 0.28 and 0.84, respectively. External validation found no statistically significant difference between the MMA test results from the two independent laboratories.

One of the leading contributors to preventable illness and mortality has been found to be cigarette smoking. \u0000Aim: The goal of this study is to evaluate a few haematological metrics among smokers in Port Harcourt, Rivers State, and to verify the idea that smoking cigarettes either has a negative or favorable impact on these variables. \u0000Methodology: In this cross-sectional study, 100 participants between the ages of 20 and 45 were included, 50 of whom were smokers and 50 non-smokers. Venipuncture was used to obtain blood samples from the patients, which was then put into an EDTA vial for a full blood count (FBC) and other haematological analysis. The full blood count and erythrocyte sedimentation rate (ESR) were done using Haemo Auto Analyzer, Model XP-300 KOBE Japan by SYSMEX and the Westergreen method respectively.  In order to analyze the data, Graph Prism Pad 6.2 and Microsoft Office Excel 2016 were both used. Using the student's independent t-test, a comparative study of mean and standard deviation values for the various parameters for test and reference ranges was conducted. \u0000Results: According to the findings, the average age of 50 smokers was 43.6200± 9.7250 years and that for the 50 non-smokers was 42.7800± 6.5440 years, which was statistically insignificant with p valve of 0.6130. Smokers’ haemoglobin level was 14.5080 ± 1.5590 (g/dL) and non-smokers was 12.1340 ± 0.70410 (g/dL). According to statistics, the level of Hb was significantly higher in smokers compared to non-smokers (P<0.0001). In comparison to non-smokers, the RBC count dramatically increased in smokers (P<0.0001) greater than in non-smokers at 5.2550 ± 0.6629 (x1012/L) and 4.6340 ± 0.5530 (x1012/L) respectively. While the total leucocyte count (TLC) in smokers is 8.0500 ± 1.8796 (x109/L), compared to 6.8580 ± 1.2454 (x109/L) in non-smokers. Statistics show that smokers have a higher total leucocyte count than non-smokers (P<0.0002). Smokers' platelet count is 255.7600±61.8351 (x109/L) while non-smokers' is 216.5800±35.5752 (x109/L).The study has statistically shown that smokers' platelet counts rose considerably in comparison to non-smokers (P<0.012). \u0000Conclusion: It may be concluded that uninterrupted smoking has an undue negative impact on haematological parameters such that increase occur in values of Hb, RBC, TLC and platelets. Significantly, these changes may increase the risk of serious health issues such as heart related defects, hardening of the arteries, Vaquez-Osler disease. It is recommended that smokers have these metrics regularly monitored.","PeriodicalId":249518,"journal":{"name":"International Blood Research &amp; Reviews","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129530559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
